Thermomechanical processes in compliant damping elements
Pešek L., Půst L., Vaněk F.
pages 233 - +9p., full text

Effect of increase of heat in the rubber-like materials with high inner damping during repeated deformation is investigated. Rheological properties e.g. stiffness and damping of such materials depend considerably on temperature. Knowledge of complex modulus properties of polymeric damping materials are strongly needed for the design of systems suppressed to vibrations, for the control of vibrations and noise. Simplified mathematical model of two degrees of freedom is analysed from the point of view of lost energy, heat transfer between inner and outer part, cooling of the surface and changing stiffness and inner damping. This model is the first stage for studying of thermomechanic interaction in the 3D form of damping elements by FEM.
